Description
Technical Field
The invention relates to a runway disc device of a braiding machine, in particular to a powder metallurgy die-casting braiding machine runway block.
Background
At present, in the manufacturing field of a knitting machine, a run-in disc is composed of a plurality of independent runway blocks, the runway blocks are the most difficult to manufacture in the manufacturing process of the knitting machine, and the manufacturing difficulty of the runway blocks is equal to more than 90% of the manufacturing process of the whole knitting machine; the time, effort and cost he has, is also considerable and, more importantly: knitting machine track blocks are an important part of knitting machines which are most easily damaged, once one track block is damaged, the whole knitting machine cannot be used, replacement and maintenance are needed, and the whole knitting machine wire factory needs to be shut down and production is stopped.
Disclosure of Invention
The track disc and track block of the braiding machine are difficult to manufacture, high in cost, easy to damage, difficult to maintain and the like; the invention provides a powder metallurgy die-casting forming braiding machine track block, which is convenient to manufacture, simple in process, high in production efficiency and low in cost, the whole braiding machine track block is formed by powder metallurgy die-casting instead of cast iron, the strength is higher, the shape can be changed at will, the combination angle of each track block can be changed at will, and the braiding machine track block is more suitable for mass production, so that the manufacturing cost is greatly reduced, and the economic benefit of a factory is better.
The technical scheme adopted by the invention for solving the technical problems is as follows: a powder metallurgy die-cast forming braider runway block, comprising: the track block comprises a track block groove 1, a track 2, a central shaft hole 3, a track block body 4 and a track block conical edge 5; the track block is provided with a track block body 4 which is circular up and down and has conicity, the track block is provided with track block conical edges 5 which are suitable for combination according to a division angle formed by combining a plurality of track blocks at two sides of the track block body 4, and grooves which can be filled with X-shaped intersection small discs are respectively arranged at two sides of the track block conical edges 5; and the side wall of the tapered edge 5 of the track block is provided with a positioning pin and a positioning pin blind hole which are matched and combined with each other.
The runway block body 4 is produced in a powder metallurgy process, and the production process of the powder comprises the steps of powder preparation, powder mixing and the like; in order to improve the moldability and plasticity of the powder, a plasticizer such as an organic oil, rubber or paraffin is usually added.
The track block body 4 is formed by pressing in the powder metallurgy production process; pressing the powder into a required shape under the pressure of 15-600 MPa.
The track block body 4 is sintered during the powder metallurgy production process; in a high-temperature furnace or a vacuum furnace with protective atmosphere; sintering is different from melting of metals, in that at least one element is still in the solid state during sintering. In the sintering process, a metallurgical product with certain porosity is formed among powder particles through a series of physical and chemical processes such as diffusion, recrystallization, fusion welding, chemical combination, dissolution and the like; after-treatment, the sintered product can be used directly.
The invention has the beneficial effects that: the utility model provides a powder metallurgy die-casting forming braider runway block, not only makes conveniently, and the process is simple, and production efficiency is high, and is with low costs to its type changes powder metallurgy die-casting into by cast iron shaping, and its intensity is higher, and can also change its shape wantonly, and the combination angle of its each runway block can change wantonly, more is fit for the large batch production braider, thereby has reduced manufacturing cost, makes the economic benefits of mill better.

The runway block body 4 is produced in a powder metallurgy process, and the production process of the powder comprises the steps of powder preparation, powder mixing and the like; in order to improve the moldability and plasticity of the powder, a plasticizer such as an organic oil, rubber or paraffin is usually added.
The track block body 4 is formed by pressing in the powder metallurgy production process; pressing the powder into a required shape under the pressure of 15-600 MPa.
The track block body 4 is sintered during the powder metallurgy production process; in a high-temperature furnace or a vacuum furnace with protective atmosphere; sintering is different from melting of metals, in that at least one element is still in the solid state during sintering.
